What is the material of pet material, its use and advantages?

Abstract: Pet material is actually quite common in our daily life. For example, cabinet door panels are made of this material, so what kind of material is pet material? What are the uses and characteristics? Let's find out.
Pet material is actually quite common in our daily life. For example, cabinet door panels are made of this material. So what kind of material is pet material? What are the uses and characteristics? Let's find out.



1. What is the pet material?



Pet is commonly known as polyester resin, which is a crystalline saturated polyester. It is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface, creep resistance, fatigue resistance, abrasion resistance and dimensional stability. High hardness, but not resistant to hot water immersion, not alkali resistant.



2. What are the uses of pet materials?



1. Pets are widely used in daily life. In the classification of plastics, the code name of PET is No. 1, mainly in the field of electronic appliances, such as: electrical sockets, electronic connectors, rice cooker handles, etc.

What is the material of pet material, its use and advantages?

2. In addition, pet materials also have the following uses:



(1) It can be spun into polyester fiber, namely polyester.



(2) It can be made into a thin film for substrates, insulating films, product packaging, etc. of audio recordings, video recordings, and film films.



(3) It can be used as plastic and can be blown into various bottles, such as Coke bottles, mineral water bottles, etc.



(4) It can be used as electrical components, bearings, gears, etc.



3. What are the advantages of pet material?



1. The heat distortion temperature and long-term service temperature are the highest among thermoplastic general engineering plastics.

What is the material of pet material, its use and advantages?

2. Because of its high heat resistance, the reinforced PET hardly deforms or changes color when dipped in a solder bath at 250°C for 10 seconds, and is especially suitable for preparing electronic and electrical parts for soldering.



3. The bending strength is 200MPa, the elastic modulus is 4000MPa, the creep resistance and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to thermosetting plastics.

4. Since the price of ethylene glycol used in the production of PET is almost half that of butanediol used in the production of PBT, PET resin and reinforced PET are the lowest prices among engineering plastics, and have high cost performance.
